Z-D-Nle-ONp

Z-D-Nle-ONp is a protected amino acid derivative in which the amino group of D-norleucine (Nle) is masked by a benzyloxycarbonyl (Z, Cbz) protecting group and the carboxyl group is converted to an ONp ester (para-nitrophenyl ester). The molecule therefore bears a carbamate-linked Z group on nitrogen and an activated para-nitrophenyl ester at the carboxyl terminus, with stereochemistry specified as D at the α-carbon. Z-D-Nle-ONp is used as an amino-acid building block and activated ester intermediate for peptide coupling and related synthesis workflows, where the ONp ester provides a leaving group suitable for forming amide bonds under appropriate conditions.
